Lupinus texensis Hook.
Texas bluebonnet, Bluebonnet, Texas lupine, Buffalo clover, Wolf-flower
USDA Symbol: LUTE
USDA Native Status: L48 (N)
Texas lupine has larger, more sharply pointed leaves and more numerous flower heads than similar lupines. Light-green, velvety, palmately compound leaves (usually five leaflets) are born from branching, 6-18 in. stems. These stems are topped by clusters of up to 50 fragrant, blue, pea-like flowers. The tip of the cluster is conspicuously white.
This is the species often planted by highway departments and garden clubs and is one of the six Lupinus species which are the state flower of Texas.

Not only does the state flower
of Texas bloom oceans of blue, but this famous wildflower forms attractive rosettes in winter. This is the species often used by highway departments and garden clubs. If planting this species in areas where it has not formerly grown, it may be helpful to inoculate the soil with a rhizobium
(soil-borne bacteria which form nitrogen-rich root nodules) for lupines.

Plants in the genus
Lupinus, especially the seeds, can be toxic to humans and animals if ingested. Sensitivity to a toxin varies with a personís age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plantís different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil. Conspicuous Flowers:
Butterflies Larval Host:
Hairstreak butterfly, Elfin butterfly Deer Resistant:
Propagate by sowing seed or planting seedlings in fall. Seed Collection:
Allow the bluebonnet to reseed itself by leaving the seed pods intact on the plant until they turn from yellow to brown. Seed Treatment:
Scarification will hasten germination. Put seeds in the freezer overnight and then douse with boiling water to crack seedcoats. Soaking seeds overnight is also effective. Drain water, add rhizobium,
and plant. Commercially Avail:
Plants doing poorly sometimes respond to additional rhizobium
